Neuroscientists are searching for the engram within the conceptual framework established by John Locke's theory of mind. This framework was elaborated before the development of information theory, before the development of information processing machines and the science of computation, before the discovery that molecules carry hereditary information, before the discovery of the codon code and the molecular machinery for editing the messages written in this code and translating it into transcription factors that mark abstract features of organic structure such as (...) anterior and distal. The search for the engram needs to abandon Locke's conceptual framework and work within a framework informed by these developments. The engram is the medium by which information extracted from past experience is transmitted to the computations that inform future behavior. The information-conveying symbols in the engram are rapidly generated in the course of computations, which implies that they are molecules. (shrink)

Beyond the Pleasure Principle is Freud's most philosophical and speculative work, exploring profound questions of life and death, pleasure and pain. In it Freud introduces the fundamental concepts of the "repetition compulsion" and the "death drive," according to which a perverse, repetitive, self-destructive impulse opposes and even trumps the creative drive, or Eros. The work is one of Freud's most intensely debated, and raises important questions that have been discussed by philosophers and psychoanalysts since its first publication in 1920. The (...) text is presented here in a contemporary new translation by Gregory C. Richter. Appendices trace the work's antecedents and the many responses to it, including texts by Plato, Friedrich Nietzsche, Melanie Klein, Herbert Marcuse, Jacques Derrida, and Judith Butler, among many others.

This is an introductory article on sociobiology, particularly its relationship to eugenics. Sociobiology developed in the 1960s as a field within evolutionary biology to explain human social traits and behaviours. Although sociobiology has few direct connections to eugenics, it shares eugenics’ optimistic enthusiasm for extending biological science into the human domain, often with reckless sensationalism. Sociobiology's critics have argued that sociobiology also propagates a kind of genetic determinism and represents the zealous misapplication of science beyond its proper reach that characterized (...) the eugenics movement. More recently, evolutionary psychology represents a sophistication of sociobiology that attends to the mind as the "missing link" between evolution and behaviour (Cosmides and Tooby 1992, Pinker 1997).
